Some additional information:
The watch contains Patek’s automatic caliber 324 S C FUS, which in this model has been enhanced with two innovations developed by the Patek Philippe Advanced Research laboratory. The first is the Spiromax balance spring made of Silinvar, which is equipped with two terminal curves and optimized with an inner boss. It improves the isochronism of the balance in the vertical orientations of the watch. As a result, its rate accuracy ranges between -1 and +2 seconds per day — similar to the precision of Patek Philippe’s tourbillon watches. The second innovation involves the time-zone setting device, which replaces the usual pivoting articulations with so-called “compliant” or flexible mechanisms. This device, which is composed of only 12 filigreed steel parts with several intersecting leaf springs — as compared to the 37 parts used in the more traditional mechanism — transmits the actuations of the two time-zone pushers to the local time display.
